Static Load (Cor) 3.4kN
Load Capacity (kN) 12.5kN
Load Capacity (kg) 1274kg

ðŸ’ĄWhat This Means

Dynamic Load (12.5kN): Maximum force while rotating. Exceeding this causes rapid wear and failure within hours.
Static Load (3.4kN): Maximum force when stationary. Use 80% for safety.
Calculate Your Load: Measure shaft forces, belt tensions, or gear loads. Include shock/vibration factors.
Failure Warning: Overloading causes bearing raceways to crack and balls to flatten permanently.

FREQUENTLY ASKED QUESTIONS

Expert guidance for 62205 bearing applications

Bearing Selection & Replacement ▾

What makes 62205 bearing suitable for 25mm shaft applications?

62205 bearing features 25mm bore diameter with h6 tolerance (24.987-25.000mm) for perfect shaft fit and optimal performance.
Why This Matters
Proper bore fit prevents slippage, reduces vibration, and ensures maximum load transfer efficiency.
How To Handle It
Measure shaft diameter precisely and select h6 tolerance for standard applications or consult for special requirements.
Use proper installation tools to avoid damaging bearing during press-fit installation.

Can 62205 replace other 25mm bore bearings?

Yes, 62205 is ISO 15:2011 compliant and directly interchangeable with other standard 25x52x18mm bearings.
Why This Matters
Standard dimensions ensure seamless replacement without equipment modification or downtime.
How To Handle It
Verify load and speed requirements match 62205 specifications (1275.0kg (12.5kN) dynamic, 13,000 RPM).
Check seal type compatibility - open, shielded, or sealed versions available.

What's the difference between 62205 and 6205 bearings?

62205 has 18mm width vs 15mm in 6205, providing higher load capacity (1275.0kg (12.5kN) vs 14kN) and better stability.
Why This Matters
Increased width distributes loads more effectively and provides better resistance to misalignment.
How To Handle It
Choose 62205 for higher load applications or when additional stability is required.
62205 series offers better performance in applications with axial loads or vibration.
Installation & Maintenance ▾

What's the proper installation procedure for 62205 bearing?

Use proper bearing installation tools, apply force to outer ring only, and ensure shaft and housing are clean and properly sized.
Why This Matters
Correct installation prevents bearing damage, ensures optimal performance, and maximizes service life.
How To Handle It
Heat housing to 80-100°C for interference fits, use installation sleeves, and avoid hammering directly on bearing.
Professional installation can extend bearing life by 50% compared to improper methods.

How often should 62205 bearing be lubricated?

Open bearings require regular lubrication every 3-6 months; sealed bearings are lubricated for life and don't require maintenance.
Why This Matters
Proper lubrication prevents wear, reduces friction, and maintains optimal operating temperature.
How To Handle It
Use high-quality grease suitable for bearing speed and temperature conditions.
Monitor bearing temperature - increase of 15°C above ambient indicates lubrication issues.

What's the expected service life of 62205 bearing?

Under proper conditions, 62205 bearing can provide 50,000+ hours of service life with professional installation and maintenance.
Why This Matters
Understanding service life helps plan maintenance schedules and replacement cycles.
How To Handle It
Monitor vibration levels, temperature, and noise to predict maintenance needs.
Proper installation and lubrication can extend service life by 3-5x compared to poor practices.
Troubleshooting & Problem Solving ▾

Why is my 62205 bearing running hot?

Overheating usually indicates insufficient lubrication, excessive load, or misalignment issues.
Why This Matters
High temperature accelerates wear and can lead to premature bearing failure.
How To Handle It
Check lubrication levels, verify load ratings, and inspect for misalignment or contamination.
Temperature increase of 15°C above ambient requires immediate attention.

What causes excessive noise in 62205 bearing?

Noise typically results from contamination, insufficient lubrication, or bearing damage from improper handling.
Why This Matters
Unusual noise indicates potential failure and should be addressed immediately.
How To Handle It
Inspect for contamination, check lubrication, and examine bearing for visible damage.
Use vibration analysis tools for early detection of bearing issues.

How do I identify if 62205 bearing needs replacement?

Signs include excessive play, rough rotation, unusual noise, high temperature, or visible damage to raceways or balls.
Why This Matters
Early replacement prevents equipment damage and reduces downtime costs.
How To Handle It
Perform regular inspections and replace at first signs of deterioration.
Keep spare bearings on hand for critical applications to minimize downtime.
Cost & Performance Optimization ▾

What's the cost-benefit of choosing 62205 over cheaper alternatives?

62205's Gcr15 steel construction and professional quality provide 3-10x longer service life than cheap alternatives.
Why This Matters
Higher upfront cost is offset by reduced replacement frequency and maintenance costs.
How To Handle It
Calculate total cost of ownership including installation, maintenance, and downtime costs.
Quality bearings reduce total cost of ownership by 60-80% over equipment lifetime.

How can I optimize 62205 bearing performance?

Ensure proper installation, use appropriate lubrication, maintain clean operating environment, and monitor operating conditions.
Why This Matters
Optimized performance maximizes bearing life and reduces maintenance requirements.
